Why pool tanking matters
Waterproofing is a critical stage of swimming pool construction. The original Poolbuild technical guidance emphasises the importance of a watertight shell and the potential damage caused by inadequate tanking.
Spray-applied membranes
The existing article describes a spray-applied liquid membrane system installed using specialist equipment. It explains that a water-carried formulation avoids the strong solvent vapours associated with some alternatives. Suitability and installation conditions must be checked for the specific membrane being used.
Substrate preparation
The original guidance specifies solid, dry substrates and compatible renders, including a rapid-curing waterproof render. Preparation, moisture condition and compatibility are essential considerations before any membrane is applied.
Application and specification
The original page refers to two or three spray coats depending on external hydrostatic pressure. The actual number of coats, film thickness, curing period and detailing must follow the current manufacturer’s specification and project design.
Waterproofing is a complete system
Pool penetrations, joints, corners and interfaces with fittings all need careful consideration. Membrane performance should be evaluated as part of the complete pool build-up, rather than in isolation.
